In this paper, the three-dimensional compressible Navier-Stokes
equations are considered on a periodic domain. We propose a semi-discrete
numerical scheme and derive a priori bounds that ensures that the resulting
system ...

The ensemble Kalman filter (EnKF) has, since its introduction in 1994, gained much attention as a tool for sequential data assimilation in many scientific areas. In recent years, the EnKF has been utilized for estimating ...

In this thesis mathematical models with and without dynamic capillary effects are developed to model water flow and solute transport through a porous medium. The system of equations are discretised using the finite volume ...

Skjøtskift, Torgeir(Master thesis, The University of Bergen, 2015-01-05)

We explore the theory of cohomology of groups and
the classification of group extensions with abelian
kernel. We then look at the group extensions that underlie
the truncated Witt vectors on the truncation set {1,p}
where ...
